THREAD-PACKAGE.

Application filed June 7,

Toall whom.- it may concern:

Be it known that I, Cannons P. Mireil- ELL, a citizen of the UnitedStates of Americe, and a resident of Arlington Heights, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Thread-Packages,

of which the following is a specification.

This invention relates to packages of continuous thread, cord, or othersimilar materials, and particularly to those packages which are wound toa. large diameter as com pared with the diameter of the tube or core onwhich they are supported and in which 1 the number of winds oreonvolutions in the several wrappings decreases as the body of thread orother material increases on the tube or core.

The object of the present invention is to produce a package which willcontain a greater quantity of material than is generally contained in apackage that will occupy the same cubic space wound in this manner underthe usual methods.

The invention consists in making a pack age of a plurality of sectionsof which each one starts with a wrapping or helix of a certain number ofwinds, the number of winds gradually decreasing with the increasing sizeof the section; a new section being started at a convenient period witha wra ping which has a greater number of win s than those completing theprevious section, the progress of the winding in each section beingaccompanied in each section with a decrease in the number of winds perwrapping.

The invention consists further in certain. novel features ofconstruction and arrangement of parts which will be readily understoodby reference to the description of the drawings and to the claimshereinafter given.

Of the drawings: Figure 1 represents, in diagram, a tube or core havingwound thereon the initial wrapping of the first or inner section of apackage with a given number of winds, as, for instance, four (4). Fig. 2represents, in diagram, the same package at the completion of the firstsection, the exterior wrapping of which has a lesser number of windsthan the initial wrapping, as, for instance, two (2). Fig. 3 represents,in diagram, the same; package with the initial wrapping of the secondsection wound thereon, the number of winds Specification of LettersPatent.

therein being greater than that of the elite rior wrapping of the firstsection upon Q which it is wound, as, for instance, three (3). Fig. 4represents, in diagram, the complete package, the exterior wrapping ofthe second section having a lesser number of winds therein than theinitial wrapping of said section, as, for instance, one and onehalf (11;). Fig. 5 represents an end view of the same, and Fig. (3 representsan elevation of a package formed without changing the length of traverseof the thread guide during the winding.

Similar characters designate like parts throughout the several figuresof the drawings.

In the drawings, 10 represents a tube or core upon which is wound afirst section 11, which in turn has superimposed thereon a secondsection 12. Each of the sections 11 and 12 is composed of a plurality ofwrappings of thread, cord, or similar material, the number of winds orconvolutions in the initial wrapping of each section being greater thanthe number of winds in the ex terior wrapping thereof. F or instance. asindicated at 14 in Fig. 1, the initial wrapping 13 has in the length ofsaid package four winds. As the first section is built up the succeedingwrappings have. fewer winds than the next preceding wrapping received.The length traversed by the thread guide is made shorter as said packageincreases in size, thereby forming the tapered end 15. As a consequenceof this gradual decrease in the number of winds in the successivewrappings from the initial wrapping outward, when the first section ofa. package having four (i) winds in the initial wrapping thereof hasbeen built up including the tapered ends. it. will have in its exteriorwrappings 13 say two (2) winds, as indicated at 16 in Fig. and willcontain approximately the same quantitv of material as similar packageswound in this manner under usual methods. It is evident that while suchmanner of winding continues, the winds of the successive wrappings willbecome more and more separated with increasing space not occupied by thematerial.

To improve this condition and produce a package in which more materialcan be containcd in a package of similar size wound in this manner isthe object of the present invention. This is accoi'uplished by buildingup the first section as described, and changing the traverse mechanismto locate in position and increase the length of the material in theinitial wrap ing 17; Fig. 3 of the second section whic will contain anumber, of winds, say, three (3), indicated at 1'8, Fig. 3 greater innumber than that P of the exterior wrapping of the first section whichwas two (2). The second section is built up in the same manner as thefirst section, the successive wrappings having fewer winds as thewinding progresses until the ackage is completed, as shown in Fig. 4, won the exterior wrapping 17* of the second section 12 .will contain alesser number of winds than the initial wrapping 17 thereof, as, forinstance, one and one-half (1%), as indicated at 19, Fig. 4; and sincethe wrappings now contain more material and are more closely wound thanin the outward wrap ings of the first section, it is evident that filesecond section thus wound Wlll containmore material in the same cubicspace and hence-a greater rl uantity of material in the whole package.11 a package wound in this manner, the sections may be so proportionedas to contain a larger or a smaller quantity of material, as may bedesired, to change-the capacit of the package; and there will be less dierence in the density of the bodies of material in the inner and outersectionsthan heretofore in packages wound under the usual method. Wherematerial, such, for instance, as a sliver of wool, is wound into'apackage in this manner without changing the len h of traverse of theguide during the win ing of the whole package, said pack 0 will haveends similar to those shown in ig. 6, and it may be wound on a taperingor a collapsible mandrel which can be removed when the winding iscompleted. Each successive section is, in efl'ect, a body of the'material complete in itself woundu n a larger core with more material ine initial wrapping and otherwise differentiated from the next precedingsection; and as no attemptis madetocontrol the placing of the material,or the spacin of the winds, defects arising from sun 11 threads, threadsthat overrun the ends of the package, and the like, that heretoforesometimes continue to the end of the winding, will generall be confinedto the section in which said de ects occur. SlIlCB the surface uponwhich the initial 'wra -ping of the second section is wound difiers romthat of the tube or core upon which the initial wrapping of the firstsection is wound, and will vary in different packages from defects inthe winding that cause irregular formation of the packages, it must beunderstood that the number of winds in'the initial and exteriorwrappings of a section approximates the numbers specified herein. Forpurposes ofdescriptmn in each section the interior wrapping havingthemost winds,

therein is to be considered the initial wrapping thereof, and, likewise,the outer wrapping having the least winds is to be con- .sidered theexterior wrapping thereof.

The term wrapping as used herein refers to the quantity of materialwound around the package while it is advancing in one direction or theother between one point of reversal and the next point of reversalwithout regard to the number of winds therein or to the location of saidoints of reverse anywhere between the en s of the package. For somepurposes it is necessary that the tapered ends of the package should beof well-defined proportions in order that the material may be readilyunwound therefrom. It has been found in practice that a more desirableform or outllne of tapered ends can be produced in packages wound asherein described and that the waste caused by imperfectly formed ends ismaterially lessened in consequence.

The diagrams illustrated in Figs. 1 to 4 inclusive are shown greatlyexaggerated with the .ends of the outer section some distance from theendsof the inner section, but it is quite evident that there will be nosuch distance'between the two ends of the sections in practice, for itis obvious that more material can be wound upon the package when theinitial wrapping of anouter section is substantially of the same lengthon the body of the package as the outer wrapping of the section uponwhich it is wound.

It is evident that the invention is not limited to the reciseconstruction and arrangement set orth, but may be variedms desired inorder to meet diflerent conditions.

Having thus described my invention, I claim:

1. A package comprising a plurality of concentric sections, each sectionbein composed of a plurality of wrappings of t read the number of windsin each wra each section decreasing from its initia and the winds in theinitial wrapping of each seEtion exceeding the number of winds in theouter wrapping of'flie next receding section.
